    .. versionadded:: 2.0

    Parameters
    ----------
    style: :class:`~discord.InputTextStyle`
        The style of the input text field.
    custom_id: Optional[:class:`str`]
        The ID of the input text field that gets received during an interaction.
    label: :class:`str`
        The label for the input text field.
        Must be 45 characters or fewer.
    placeholder: Optional[:class:`str`]
        The placeholder text that is shown if nothing is selected, if any.
        Must be 100 characters or fewer.
    min_length: Optional[:class:`int`]
        The minimum number of characters that must be entered.
        Defaults to 0 and must be less than 4000.
    max_length: Optional[:class:`int`]
        The maximum number of characters that can be entered.
        Must be between 1 and 4000.
    required: Optional[:class:`bool`]
        Whether the input text field is required or not. Defaults to ``True``.
    value: Optional[:class:`str`]
        Pre-fills the input text field with this value.
        Must be 4000 characters or fewer.
    row: Optional[:class:`int`]
        The relative row this input text field belongs to. A modal dialog can only have 5
        rows. By default, items are arranged automatically into those 5 rows. If you'd
        like to control the relative positioning of the row then passing an index is advised.
        For example, row=1 will show up before row=2. Defaults to ``None``, which is automatic
        ordering. The row number must be between 0 and 4 (i.e. zero indexed).
